KeySchema

The complete key schema for a global secondary index, which consists of one or more
pairs of attribute names and key types:

HASH - partition key

RANGE - sort key

Note

The partition key of an item is also known as its hash attribute. The
term "hash attribute" derives from DynamoDB' usage of an internal hash function to
evenly distribute data items across partitions, based on their partition key values.

The sort key of an item is also known as its range attribute.
The term "range attribute" derives from the way DynamoDB stores items with the same
partition key physically close together, in sorted order by the sort key value.

Represents attributes that are copied (projected) from the table into the global
secondary index. These are in addition to the primary key attributes and index key
attributes, which are automatically projected.
